Title: Store/transfer system for screen information
Inventor: SAKAMOTO HIDEKI
IPC: G06F3/048
Filed: 1988-07-15
Abstract: PURPOSE:To keep the total value of the screen information to be stored in a center at a fixed level despite the increase of window sizes by decomposing an original screen into plural pieces of information which are not overlapping with each other and storing them. CONSTITUTION:A reduced screen Gx is obtained with combination of partial information 1, 3 and 6 together with a reduced screen Gy obtained with combination of partial information 1, 2, 3 and 5, and a reduced screen Gz obtained with combination of partial information 1, 2 and 4 respectively. Then a center transfers the partial information combined in response to the designated display window sizes. A terminal forms a reduced screen accordant with the due display window based on the received partial information and displays the screen. In case a window size is changed, only the partial information that is not transferred in the previous time is added and transferred to the terminal from the center among those partial information needed for production of a reduced screen having a size designated newly. Thus the total value of the screen information stored in the center is kept constant despite the increase of sizes of display windows prescribed previously.

Title: Method for discharging liquid in dehumidifying apparatus
Inventor: UENO TAKEYASU
IPC: B01D53/26
Filed: 1982-10-07
Abstract: PURPOSE:To sufficiently discharge the liquid to be discharged in a dehumidifying vessel, by closing discharge valve so as to take a delay time after the pressure feed of compressed gas to an inlet opening is again started. CONSTITUTION:A dehumidifying apparatus is constituted from such a mechanism that the pressure signal from a pressure governer diappears when compressed gas is sent under pressure to a drying chamber 13i from a compressor through a pipeline 2b and generated when pressure feed is stopped. When the pressure signal disappears, the piston of the compressor is returned upwardly and the pressure in a chamber subsequently disappears in time delay while a valve 15b is pushed up to close the chamber 13g. Because an emitting valve 15 is still opened directly after compressed air begins to flow into an inlet opening 13c, compressed air is flowed into a drilled hole 15c at a stroke from the ring shaped flowline between an outer cylinder 13a and an inner cylinder 13b through a chamber 13e and a bottom part 13h and a liquid component adhered to each part is blown off to be discharged to the outside from the drilled hole 15c.

Abstract: PURPOSE:To construct a continuous wall which is excellent in impermeability, by a method wherein muddy water and impermeable material can be injected through a hollow fixed frame from the forward end of each bit and the lower end of a hollow fixed frame, and an anvil and a driving mechanism are provided. CONSTITUTION:The upper end face of a rod 2 is struck by means of an anvil 16 through driving of a striking device 15 as a rod 2, projected from the lower end of a hollow fixed frame 1, is rotated, and this performs excavation of a ground 22. Thereafter, simultaneously with excavation of a hole, muddy water 26 is forcibly fed to a muddy water injection pipe 5 to inject it through the forward end of each bit to excavate the ground down to a given depth. An impermeable material, such as mortar, concrete, is forcibly fed to an impermeable material injection pipe 6, and is injected in a hole to replace the muddy water 26 with the impermeable material. This enables excavation of a high- precise continuous hole, enables prevention of collapse of a hole wall through injection of the muddy water 26 into the hole during excavation, and permits an increasse in an impermeable effect without being influenced by crack and a crushed band in a bedrock.

Abstract: PROBLEM TO BE SOLVED: To easily sample the operating information and fault information on a computer by outputting an interruption signal to a computer, outputting the operating information and fault information stored in the computer and storing this information in an information sampling device when the information sampling device is connected with the computer. SOLUTION: When a computer A is connected with an information sampling device B, the information sampling device B outputs an interruption signal to a computer A and requests the release of the main bus 5 of the computer A. When the main bus 5 is released, the computer A notifies the information sampling device B that the main bus 5 is released and notifies an operator of the effect that an information sampling is performed. The information sampling device B samples working information and fault information from the storage device 2 of the computer A and stores this sampled information in the storage device 112 of the information sampling device B. Thus, the operating information and fault information on the computer A can be easily sampled without depending on the operator having techanical knowledge.
